New study to predict future shape of coastline

An ADCP frame will be used to measure turbulence and sediment transport

A new experiment is under way that will help forecast the shape of the Dutch coastline under changing climate conditions, involving scientists and engineers from the National Oceanography Centre (NOC).

Climate change clues from tiny marine algae – ancient and modern

Microscopic ocean algae called coccolithophores are providing clues about the impact of climate change both now and many millions of years ago. The study found that their response to environmental change varies between species, in terms of how quickly they grow.

European flood risk research recognised by Lloyd’s of London

High tide in South Devon

To understand the risk of coastal flooding, you need to understand the tides. This was a key message of a study by researchers based at the National Oceanography Centre in Liverpool and Southampton, which was short-listed for the recent Lloyd’s Science of Risk Prize.

Warming climate makes tropical cyclones more frequent

Are there more tropical cyclones now than in the past – or are we just hearing more about them through media, and detecting them more successfully with satellites?

Weighing the ocean

UK oceanographers have thought of a novel way to measure the global ocean – weigh it. In research published this week, scientists from the National Oceanography Centre in Liverpool and Newcastle University have proposed an idea that will assess the mass of the world ocean by weighing at a single point.

Classic Maya Civilization collapse related to modest rainfall reductions

A new study reports that the disintegration of the Maya Civilization may have been related to relatively modest reductions in rainfall.

Measuring sea-level rise in the Falklands

Sea levels around the Falkland Islands in the South Atlantic have risen since the mid nineteenth century and the rate of sea-level rise has accelerated over recent decades, according to newly published research. The findings are as expected under global warming and consistent with observations elsewhere around the globe.

Geo-engineering and sea-level rise over the 21st century

New national centre covers marine science from the coast to the deep ocean

Scientific findings by international research group of scientists from England, China and Denmark just published suggest that sea level will likely be 30–70 centimetres higher by 2100 than at the start of the century.
